/NVENTOH A TTOHNE YS UNITED HERMAN ZERR, OF NEW YORK, N. Y.

REFRIGERATOR.

To alt whom it may concern:

Be it known that I, HERMAN Zena, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of N ew York, have invented certain new and useful Improvements in Refrigerators, of which the following is a specifics tion.

My invention relates to refrigerators and has for its object to provide a means for keeping the air therein at a uniform temperature and to minimize waste of the freezing medium.

Other objects of my invention will appear from the annexed description and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawing in which- Figure l is a longitudinal section of a refrigerator with my improvements applied thereto; Fig. 2 is a section thereof on line 2-2 of Fig. l, Fig. 3 is a section on the line of Fig. l, and Fig. 4 is a sectional view of another form of receptacle.

A is the refrigerator, the walls and top and bottom of which may be of the usual construction and which is provided with the customary door A for entrance and exit therefrom. On each of the side Walls of the refrigerator I have secured a shelf B held in position by braces C and provided with rollers D for the purpose to be described hereinafter. Each of these shelves B is provided with gutters E and E running lengthwise thereof and inclined toward the front of the refrigerator as shown in Fig. l. Beceptacles F are arranged to be supported on the shelves B and to travel on the rollers l). These receptacles F are guided on the said rollers D by the flange B of the shelves B and the projection Gr on each of the side Walls of the refrigerators. The receptacles are preferably made with corrugated sides as shown and are adapted to contain a freezing mixture, as for instance a mixture of ice and rock salt. Each of the said receptacles F is provided with a removable cover F having at each end projections F5. Bolts F2 are pivoted at Fx to the receptacle and are provided with nuts adapted to engage the projections F5 to secure the cover in position. A gasket H of rubber or similar material is located between the said covers and Specification of Letters Patent.

the upper edges of the receptacles so as to insure a tight joint at these points when the covers are secured in position. Each receptacle F is provided with a d `ain cock F3 which extends over the gutter E so that as the freezing mixture melts the water will run off from the receptacles into these gutters. Tubs or troughs I extend beneath the gutters E and E at the lowest end thereof, Which troughs receive any water which runs into the gutters from the sides of the receptacles F or which runs from the said receptacles through the drain cocks F3 as the freezing mixture therein melts. These troughs I are suitably connected as by a tube I with the sewer.

An opening J is arranged in the front wall of the refrigerator adjacent to each shelf B and is closed by a door J. '.lhns when it is desired to replenish the freezing mixture in either of the receptacles l", the door J is opened and the particular receptacle F is drawn through the opening J after which the-cover F is removed and a new supply of freezing mixture is introduced into said receptacle. Each receptacle F is further provided at its rear end with a projection F'1 which completely closes the opening J during this replenishing process. This arrangement prevents any warm outer air from entering the interior of the refrigerator during the refilling of the receptacles'. The temperature of the refrigerator is thus maintained at a uniform point and waste of freezing mixture is done away with. The receptacles F are also practically air tight when the covers F are in position so that the freezing mixture contained therein melts very slowly and thus .maintains its efficiency for a long time. By having the receptacles F arranged away from the side walls of the refrigerator through the medium of the projection G and by providing the shelves B with openings B2, the sides, ends and top and bottom of said receptacles all ope 'ate to abstract heat from the air in the refrigerator. The rollers D serve to minimize the friction when the receptacles F are withdrawn from or replaced in the refrigerator. A compartment K may be supplied for the purpose of containing ice for other purposes than cooling of the air in the refrigerator7 as, for instance, for cooling beverages etc. An opening L closed by a door L is provided for the purpose of communicating wit-h the compartment K.

In the form of my invention shown in Fig. l I have provided the receptacle F with a dome like partition which divides the said receptacle into two chambers f and f2. The partition f is so constructed as to leave spaces f3 between a portion of it and the sides of the receptacle so that the freezing mixture contained in the chamber f will practically surround said partition. The chamber f2 is adapted to contain game or other articles which are to be frozen, an opening f* being provided for the purpose of introducing the game into said chamber f2. This opening f* is normally closed by a door f5. The liquid, due to the melting` of the freezing mixture is adapted to run from the receptacle into either of the guttersv E or E through a suitable drain-cock f. In all other respects this form of receptacle may be the same as hereinbefore described.

By making the sides of the receptacle corrugated as shown, the area thereof is increased without necessitating a bulky or cumbersome construction.

While I have shown and described a refrigerator provided with two receptacles F, I desire it to be understood that in many casesone such receptacle will be sufficient; if desired, however, more than two such receptacles may be provided.

With my improvements I secure an even I and effective temperature in the refrigerator with a minimum freezing medium, thus saving in the cost of ice, and I also economize in space, as my device does not take up nearly as much room as the ice compartment used at present, 'while rendering more eflicient and satisfactory service.

Various modifications may be made without departing` from the nature of my invention as defined-in the claims.

I claim: Y

l. A refrigerator comprising' a box having an opening, an interior runway having its one end adjacent to said opening, troughs ruiming' lengthwise of said runway at opposite edges thereof, a longitudinalv flange on said runway adjacent to one of said troughs, rollers journaled on said runway, a receptacle for a cooling agent provided with corrugated side walls, and adapted to travel on said rollers, said receptacle being arranged for projection through said opening and to be guided by said flange at a distance from the wall of the refrigerator and a removable cover for sealing the said receptacle.

2. A refrigerator comprising a box having an opening, an interior runway comprising spaced connected members and having its one end adjacent to said opening, troughs running lengthwise of said runway at opposite sides thereof, a longitudinal flange extending upwardly from said runway adjacent to one of said troughs, a projection on the side of wall of the refrigerator above `said runway, a receptacle for a cooling agent arranged to travel on said runway between the projection and the flange and to be projected through said opening and means on said receptacle for closing said opening when the receptacle is fully projected.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
